Cannot open include file: ui_*.h when using multiple Qt projects in the same Visual Studios solution
-
I'm trying to use a header file from one Qt project that includes the associated ui_myDialog.h file in a different Qt project in the same solution. The project that has this header file creates the ui_myDialog.h file successfully and builds fine, but when I try to use this header file in the other project, it is unable to build and gives me fatal error C1083: Cannot open include file: 'ui_myDialog.h': No such file or directory. Any help or insights with this issue would be much appreciated. Thank you.

Since the file is generated it's not in the source but in the build dir. So either include this directory or better forward declare the Ui::Dialog class und use a pointer to it (Ui::Dialog *m_ui) so you don't need to include the generated ui header file in your header at all.

Thank you very much for your help. I included the build directory and set the project dependencies accordingly. This fixed the issue.

My second solution would be much more portable.
